Since nobody here seems to want to answer your question
(or seems even able to read it), I'll try. Is something
like this what you want?
import re
texts = [
'(i)"In the ocean"',
'(ii)"On the ocean"',
'(iii) "By the ocean"',
'(iv) "In this group"',
'(v) "In this group"',
'(vi) "By the new group"']
pattern = re.compile (r'^\((.*)\)\s*"\S+\s*(.*)\s\S+"$')
for txt in texts:
matchobj = re.search (pattern, txt)
number, midtext = matchobj.group (1, 2)
print ("(%s) %s" % (number, midtext))
